.50 arent as bad as everyone seems to think they are. we used one at our feild to try it out and I was impressed. Slight less range but I would bet most people couldnt tell the difference its so slight. The only real problem we encountered was when we went to the upper more wide open corses you could see the ball was more effected by the wind then the .68 but it was very windy that day. OUtside of that there wasnt much difference.
